摘要： PROBLEM TO BE SOLVED: To easily respond to the dimensional change by attaching a cutting blade having a tip for cutting a burr to a cylindrical tool main body having a plurality of slitting grooves. SOLUTION: A position of a cutting blade 35 is adjusted by a screw 36 in response to the outer diameter of a metal conductive material 22. After that, the metal conductive material 22 is inserted inside a cover 32 till the tip 37 reaches the position of a burr 23. The tool main body 31 rotated manually so that the burr 23 stuck to the outer circumference of the metal conductive material 22 is cut over the whole circumference. Slitting grooves 34 are provided at equal intervals in the circumferential direction in the tool main body 31 and the cover 32. This constitution provides the tool main body 31 with a spring property so as to make the tip 37 surely bite into the burr 23 and respond to the change in the outer diameter of the metal conductive material 22.

摘要： PURPOSE:To provide a casting mold which facilitates optimum temperature control for effecting optimum molding, provided with an easily adjustable temperature control device by providing a water receiving container for use in controlling temperature in molten cast resin above a sprue of a casting mold so that the container is dipped into the resin. CONSTITUTION:Molten casting resin 4, in the form of liquid, is poured into a casting mold 10 so that the resin reaches a resin holding section 7, so that a water receiving container 11 for controlling temperature is dipped into the resin 4 in the holding section 7. The mold 10 together with a temperature con trol device including the container 11 is put into a constant temperature bath having a temperature of 130 deg.C or higher. The casting resin 4, thermosetting resin, begins to harden at a high temperature. Since the container 11 is placed in the resin 4 in the holding section 7, optimum specified temperature distribu tion is achieved in a molding section 10a below the sprue 5. In the sprue 5 and section 7, the resin 4 is maintained at a temperature such that the resin 4 is not solidified and for compensating the contraction of the resin 4 in the section 10a due to solidification of the resin 4, the resin 4 in the section 7 is supplied through the sprue 5 to produce a suitable molded item.

摘要： PROBLEM TO BE SOLVED: To eliminate burrs from generating in a casting mold and dispense with cracks due to the burrs and operation to remove burrs from the casting mold. SOLUTION: A bush 11 encircling a part where a metal conductor 4 penetrates a resin (corresponding to a cavity 3 part) is provided, and the outer peripheral side of the bush 11 is surrounded by a casting mold. Since the coefficient of linear expansion of the bush 11 is set higher than that of the casting mold, the bush 11 is expanded not only to the outside, but also to the inside by the casting mold which holds the bush 11 at the time of cast molding. Thus the bush 11 comes into close contact with the metal conductor 4 to prevent burrs from being generated.

摘要： PROBLEM TO BE SOLVED: To provide a method for correcting the inner dimension of a hollow cast item to a required dimension and provide a correcting jig for use in executing the method. SOLUTION: In the correcting jig 1, a nearly cylindrical supporting rod 3 is erected at the center of a base 2 having a crossed shape, in a plan view, and a correcting plate 4 comprising a circular aluminum plate having a predetermined diameter is attached to the vicinity of the upper end of the rod 3. After being heated and hardened, a cast isolation cylinder 11 having a temperature of about 80 deg.C is fitted on the plate 4 so as not to contact it to mount the edge of an opening of the cylinder 11 on supporting parts 21, 21, 21, 21 of the base 2. At that moment, gaps between the plate 4 and the cylinder 11 are kept approximately constant over the entire periphery of the plate 4. Under such conditions, the temperature of the cylinder 11 is cooled to reache a room temperature.

摘要： PROBLEM TO BE SOLVED: To eliminate preparatory work and to prevent the deterioration of the machining precision of a casting insulating material by a method in which the upper part and the one end of each column are connected, the peripheral part of an upper plate is pressed elastically by the other end, and a pressing apparatus is provided which is formed openably/separably with the peripheral part of the upper plate. SOLUTION: A casting insulating material 23 is arranged between a lower plate 17 and an upper plate 26, the peripheral part of the upper plate is pressed by the first pressing apparatus 35, and a correcting jig of a casting insulating material 23 which pressed the other end of a conductor 25 by the second pressing apparatus is mounted on a roller conveyer, transported to a heating oven, and heated to a strain removing temperature in the oven. The jig is taken out from the oven after the completion of heating and cooled gradually by radiation so that the correction of the insulating material 23 to correct a casting resin 24 is carried out to the precision of the lower plate 17 and the upper plate 26. When the insulating material 23 is cooled after heating, a casting resin 24 is pressed by the first pressing apparatus 35 following the shrinkage.
